Meta element

about 20.180. This element was discovered by Sir William Ramsay in 1898 and contributions also came from Morris Travers. I will go into greater detail about how they discovered neon later into the essay. Neon’s atomic number on the periodic table is 10. It is also odorless, colorless, and non-toxic. As I stated earlier, neon was discovered at the University College London by Sir William Ramsay and Morris Travers in 1898. However, this was not the first element discovered by Ramsay…

Phosphorus (chemical symbol P) is an element that comes in the form of three allotropic. A white waxy solid, a red powder or black powder .White phosphorus is poisonous and when it comes in contacts with air (0) it can spontaneously ignite, which is why white phosphorus is stored in water (figure A). Phosphorus boiling point is 280°C and a melting of 44°C. When phosphorus is boiled it forms a red powder (figure B) which is found in the head safety matches (figure C). Black phosphorus is created…

Chemical contamination refers to the contamination of the environment with chemical substances, there are many chemical contaminants, and some of them are volatile found in our environment. Benzene is one of them, it evaporates rapidly, it smells sweet, flammable, colorless liquid, it presents in gasoline, crude oil, and cigarette smoke. Benzene is one of the chemical contaminant which used in manufacturing many products like plastics, synthetic fibers and resin. Also, it is used to solve waxes,…

Carbonation is another type of chemical weathering. Carbonation is the mixing of water with carbon dioxide to make carbonic acid. This type of weathering is important in the formation of caves. Dissolved carbon dioxide in rainwater or in moist air forms carbonic acid, and this acid reacts with minerals in rocks. chemical weathering tends to be different sorts of chemicals mixed together to form a material. Rust is a good example of what chemical weathering can do. With an increase in…

("Neon," 1999). In 1898, a Scottish chemist Sir William Ramsay (1852-1916) and English chemist Morris M. Travers (1872-1961) discovered neon just after they discovered the element krypton that same year. ("Neon," 2000). Physical Description Neon is the second element in Group 18 of the periodic table, a group of elements known as the inert or noble gases. Neon’s chemical symbol is Ne and the name neon is taken from the Greek word neos meaning "new". The boiling point of neon is -410.94°F…

The purpose of this lab was to determine the formula of copper chloride hydrate by dehydration through heating, rehydration through adding water back in, the reaction of aluminum with the copper chloride hydrate to produce solid copper, and the weight of this copper. To accomplish this, a petri dish was weighed and 1.01 g of copper chloride hydrate was added to the dish. The solid salt crystals were broken up to make sure that all of the hydrate would be heated the same. Next, the petri dish and…

People everyday experience confusion as to the meaning of a sentence based upon incorrect comma placement. There was actually a legal case in Maine over the misuse of commas, particularly the Oxford comma (Sullivan). The Oxford comma is the labeled “optional” comma after the last item in a list and before the word “and”. Some people believe that the Oxford comma is unnecessary, but that is simply incorrect. The usage of this particular punctuation is considered optional by many, but given the…

Purpose The purpose of the experiment that the students are conducting is to determine the empirical formula of the copper chloride hydrate by the data that has been collected throughout and that will allow the students to “investigate the effect of heating a hydrate salt” (Sanders). This will be achievable after finding the masses of chlorine, copper, and water. Introduction In this experiment, the students are using the law of multiple proportions to find the chemical formula for the compound…

most interesting. After doing some research on the boom I found that it had great reviews online, and was one of the top ten most recommended books in the chemistry genre. This book caught my attention because it gave a brief history of many of the elements, and I was keen to learn how to incorporate chemistry into my daily life. Synopsis- The Disappearing Spoon starts off with an introduction in which Sam Kean narrates how he fell in love with the science of chemistry, because as a child he…

It is an element. It is rare. It is Hassium. Out of a total of 118 elements on the Periodic Table of Elements, Hassium is just one. Hassium is the 108th element on the periodic table. Have you ever heard of Hassium? The term Hassium was derived from a german state of Hesse, where Hassium was first made. Hassium was discovered in 1984 by Peter Armbruster and Gottfried Munzenburg. These two inventors developed this element in Darmstadt, Germany which is located in Europe. Hassium has a…
